Abstract

A connection cap (160) for connecting rechargeable batteries in a battery module is provided. The connection cap includes a cap base having a rim and at least one indentation (163) formed on the rim. The connection cap further includes a cover including a side wall protruding from the cap base and having at least one opening (167) through the side wall.

Description

technical field [0001] The present disclosure relates to a battery module, and more particularly, to a battery module improved to counteract an external force applied to a rechargeable battery. Background technique [0002] Typically, battery modules are constructed using multiple rechargeable batteries connected to each other. Rechargeable batteries can be repeatedly charged and discharged due to the reversible interconversion between chemical energy and electrical energy. Recently, with the development of portable wireless electronic devices, there has been an increasing demand for rechargeable batteries with high energy density in order to make these devices small in size and light in weight. [0003] Examples of widely used rechargeable batteries include nickel-cadmium batteries, nickel-hydrogen batteries, and lithium rechargeable batteries. Specifically, the operating voltage of lithium rechargeable batteries is greater than or equal to 3.6 V, which is three times hig...
